I would need to reset the multi-factor authentication for my Phabricator account. The reason is that I've lost the cellphone where I had my 2FA/TOTP app. I'm currently logged in to Phabricator but will soon need to reinstall the operating system on the computer due to failing hardware. My Phabricator user page can be found here: https://phabricator.wikimedia.org/p/Tommy_Kronkvist/ and that page includes a user committed identity hash for my account. I added the user committed identity hash to my user page quite some time ago, and is also present on several of my user pages for different Wikimedia sister projects. My Phabricator user page also includes a link to my public PGP key which I use to sign (and occasionally encrypt) my email: tommykronkvist@me.com. My Phabricator account is connected to my MediaWiki user account, and that same email adress is used for both my Phabricator account as well as all the many Wikimedia sisters projects I'm active in.
Per https://www.mediawiki.org/wiki/Phabricator/Help/Two-factor_Authentication_Resets I hereby explicitly ask for creating a custom private Paste to verify my user committed identity hash. (I don't really know how this works, but hopes that the community will help me :-)
For reference, I'm an administrator, bureaucrat and interface administrator at Wikispecies, an administrator at Swedish Wikivoyage, and an administrator at Wikimedia Sweden (i.e. "WMSE", the Swedish Wikimedia Chapter).

I'm sorry if I'm going about this in the wrong way, but the information on the "Two-factor Authentication Reset" page isn't crystal clear.
